T o all whom it lmay concern:

Be it kn'own that I,

oiEHi., a citizen of the United States, and

,ployed to cover" and support battery. elements within a jar.

i It isthe purpose otythe invention to i ro'-V vide acoiiibiiied cove'r and attached insu ating sleeve to which different types of elements may be detacliably connected and in a way to insulate them troni each other; `further to provide means for preventing the deposits on the oil covered .solution from bridging over fromoiie element to the other and short circuiting the battery. a cover having a detachable sleeve to extend below the solution line, and which is adapted for any of several well known types ot elements now upon the market including some of my .own design .as for instance that show` .i1 in the drawings forming a part ot'this application. i

With the above and other minor objects in view my invention resides and consists in the no vel construction andv` combination ot' parts shown upon the accompanying drawing, upon which similar letters ot' reference denote like or corresponding parts throughoutthe several figures, and of which,

Figure 1, shows aside elevation of my iinpro'ved cover complete and having a couple of elements attached thereto as in use, the. out-lines of a jar being indicated by dotted lines. Fig. 2, is a central vertical cross sectioi'i, on a' reduced scale, of the cover shown in Fig. il. Fig. 3, shows asimilar sectional view ot :i slightly modified construction ot cover.

In the carrying out of my invention I may construct the cover proper of porcelain, rubber, iiberor metal or any ot the well known cover materials, 'and said cover may be adapted to set in or over the jaras preferred.

In the operation oi' batteries of 'this classv vit is essential that the negative element should' be positively retained in substaii tially the positioiishowii, with relation to both' the zinc and cover. l`lieieioie it is iiccessar.' to ii'ovidc an extended su i ioi't which Specification of Letters Patent application filed May 29, 1905. .Serial No. 262,953.

To provide Patented May 5, 190e.-V

Willrmly hold the element vcentral within the zinc ring andprevent it contacting with the same, and'forconvenience-aiid clieapn'ess ofl manufacture Iv-have provided a detacha `l extension for attachment to the undersid the cover which is `formed of insulating@ terial, preferably annular in shapey andgiiiiaI length equal to the desired distance betw en A the coverand negative element. s Referring in detailtogthe reference chal?- acters marked upon the drawings' A indi-p. Cates the coverI as a whole, which as indi` cated in Figs. 1 and 2 is formed of porcelain v and contains an annular rib B on itsiinder- 'side to engage the inside of the. t-op .edgeiof the battery jar. This cover also fcpntains holes C-C vtherethrough for the attachment of the positive element, as for instance a zinc D. The zinc D shown is one of my improved types, comprises a cylindrical or annular body portion adapted to encircle the negative element. It is further provided with suspending rods E-E formedintegral therewith, having a reducedfendto' pass through 80 the holes C before mentioned, and .a shoulder F which fetches up against the underside of the cover.v A nutl G engages the reduced threaded endot each of these rods for the atv tachment of the saine to the cover, andanut H forms the binding post connection for the' field wire, (not shown). It' preferred, as in case of the employment ofa niet-al cover, as shown in Fic. 3, I provide a detachable iti-- sulating bushing I, which is formedl of two parts and has a hole J therethrough for the attachment of azinc. One of these parts has a reduced threaded end to pass through the hole of the coverl and the other a nut to engage and cover-said threaded end in a way to clanip'the bushing firmly to the cover. The negative element K shown in the middle of the zinc D is aompressed cylindrical element ot improved type, and is suspended i from the cover and againsttlie extension L by an electrode-supporting rod M secured by nut and provided with a binding screw rI`lie `detachable insulating extension is iii the form of a depending annular sleeve, liich is longitudinally extended as shown in Fig.

1. and serves first as an insulator for the rod )I and 'second as a shoulder or stop against which the negative element is fastened. This extended sleeve like the bushings for the siis` pending rods of positivecleiiieiits is made detacliahle and contains a central hole l therethrough for the rod .\lbefore mentioned'.

' This extended sleeved; may be made detach-- AFig.v 2, or tapered as `shownin Fig. 3, to

' ceiye the cylinder, rod connections', etc. This Vsleeve may be of any deslred length, but ..15

f element from shifting-its'position and con- 25 preventing any possibility of the inetallic ofthe position 'of the zinc'. A Itxes the posi# vtion-or :distance of the element from the lighten the construction and properly reregulated to. a degree by the relative .location cover, and is also 'made sufficiently broad to forni a rigidshoulcler for the element secured aga-inst its lower. end, thus preventing said tacting with the zinc. It Willalso be Seen that this sleeve serves es ay protective insulater for the rod of the compressed element l formation on the surface of the oil covering the solution` see dotted lines S Fig. 1) producing a'contact between the poles of the two elements and thereby short cireuiting the same. f

I claim 'and desire to Secure by Letters Patent is The' combination with an electrode, of an electrode-supporting device, comprising a depending longitudinally extended protect'- ing-sleeve having a shouldered and threaded upper portion), a member having a threaded recess extending partiallytherethrough, and

a perforation continuing tl1erefrom-and- 3 0 Having thiis described my invention WheJ adapted to register with the opening through i said sleeve.
